LUBRICATING DEVICE.

Specification of Letters Patent.

Patented Feb. 14, 1911.

Application filed. December 17, 1909. Serial No. 533,708.

To all whom it may concern:

Be it known that 1, JOHN D. CoNNnR, a citizen of the United States,residing in Philadelphia, county of Philadelphia, State of Pennsylvania,have invented certain new and useful Improvements in LubricatingDevices, of which the following is a specification.

My invention relates to improvements in lubricating devices, and it hasfor its object to provide means by the use of which a shaft, piston rodor similar object may be constantly lubricated with a minimum of costconsistent with efficient and complete lubrication.

My invention may be applied in many ways and to different objects but asa convenient means of illustration I have shown it as applied to theplunger of a hydraulic elevator of the direct plunger type.

My invention, broadly speaking, comprises an improvement in the meansfor supporting and holding greater or less quantity of lubricatingmaterial in a receptacle through which the plunger, piston rod orsimilar object operates.

A convenient embodiment of my invention is illustrated in theaccompanying drawings but it is to be understood that changes in thedetails of construction may be made and that diiferent applications ofthe said invention may also be made without departing from the scope ofmy invention as the same is hereinafter set forth.

In the drawings :-Figure 1 is a side elevation of a lubricating deviceembodying my invention, the said device being supported upon an elevatorplunger, a portion only of which is shown; Fig. 2 is a longitudinalsection of the same; Fig. 3 is a view of an edge of one of the sectionsof which the lubricant holding receptacle is composed; Fig. 4 is atransverse section of a portion of the said receptacle somewhatenlarged; Fig. 5 is a view of a bolt and wing nut employed for securingthe sections of the receptacle together; and Fig. 6 is a view in sideelevation of a portion of the receptacle showing a modified constructionof means'for securing the edges of the parts forming the receptacletogether.

ject such as a piston rod. A. cover 3 is provided for the saidreceptacle, the said cover constituting practically a portion of thesaid receptacle.

In the constructionshown the body portion 1 and cover 3 each consists oftwo members or parts. The edges of each member or part are provided withangle irons 5, one flange of each of which is secured to the respectivemembers or parts of the receptacle and cover while the other flange ofeach of the said angle irons extends outwardly as clearly shown in Figs.1 and 3 of the drawings. The parts or members of the body portion 1 ofthe receptacle and its cover 3 are secured together around the part tobe lubricated by means of bolts 6 and wing nuts 7 ,-the bolts extendingthrough slots 8 in the outwardly extending flanges.

While the body part 1 and the cover 3 of the receptacle are each made upof two parts or halves it will be understood that this is merely amatter of convenience and economy and that a greater number of parts maybe employed for constructing the members 1 and 3 of the receptacle.

The cover 3, as will be noted, is, generally speaking, of truncated coneshape and its lower edge is provided with a flange 10 which extends overand around the upper edge of the member 1 of the receptacle. The saidcover 3 is secured upon the main or body portion 1 of the receptacle bymeans of spring catches 9 fastened to the body portion 1 and which areadapted to extend over the outer peripheral edge of the said cover inthe manner shown particularly in Figs. 2 and 4 of the drawings.

The upper edges of the cover 3 are provided with flanges 11 to which aresecured holders 12 for packing material 13 which is adapted to besaturated with the lubricating material in the receptacle 1. WVhile thesaid holder 12 is rectangular in cross section, it will be understoodthat it may be of any other cross sectional contour desired.

It is desirable that the cover 3 be inclined as shown for the reasonthat when so inclined it will shed water, dust, etc, instead ofcollecting and holding it as it would if the cover were horizontal orconcaved. I have also found by experience that if the surface of thelubricant is located in close proximity to the cover of the receptacle,it is diflicult to prevent too large a quantity cated, T have found thatwhile the lubricant 7 may be lifted by the piston rod or similar objectas it passes through the same, such lubricant is returned into thereceptacle by the cover.

From the lower edge of the central portion 14 of the receptacle 1 itssides are inclined inwardly and downwardly toward the plunger 2 orsimilar object as indicated at 16. The lower edges of the receptacle 1are flanged as at 17. The collar 18 surrounds the part 2 adjacent to theedges of the lower end of the receptacle 1. The portion of the saidcollar next to the receptacle 1 is provided with a groove 20 adapted tohold packing material 21. The said groove is illustrated as beingrectangular in cross section but it may be of any other contour desiredand is formed by stamping or pressing the metal of the collar to theshape desired. The flange-like portion 22 constituting one side of thegroove 21 is secured by means of rivets 25 to the flange 17.

In the construction shown, the collar 18 consists of two parts ormembers but may consist of a greater number if desired. Angle irons 26are secured by means of rivets to the edges of the parts or members ofthe said collar and the said parts or members are secured and heldtogether about the part 2 by means of bolts and nuts in the same manneras the parts of the body portion 1 and cover 3 of the receptacle aresecured and held together.

The lower edge of the collar 18 is adapted to rest upon a gland 29 whichsurrounds the part 2, which in the drawing is a portion or section of aplunger of a hydraulic elevator. The said gland is held in position andmay be tightened or moved downwardly by means of bolts 30 and nuts 31,the said bolts having screw-threaded connection with a packing orstuffing box 32 which, in the construction shown, is formed .integrallywith the head 33 of a cylinder (not shown). The packing 35 is located inthe said stuffing box and held in position by the gland 29. The stutlingbox is provided with an angular flange 36 forming a receptaclesurrounding the part 2 for the purpose of catching water, grease, etc.

By providing an elongated collar such as 18 the receptacle is held awayfrom the stulfing box 32, gland 29, etc., to permit access thereto forthe purpose of tightening or loosening the gland holding nuts, attendingto the packing 85 and for similar purposes. efficient and perfectlubrication of the rod or plunger which it surrounds by reason of thefact that a suflicient quantity of lubrieating material escapes from thelubricant lubricating material between the said collar and the said rodor plunger.

In order to prevent movement of the reis shown, for instance, in Fig. 2of the drawings, when the part 2 is moved outwardly through the saidreceptacle, I have provided holding stays or rods 41 having hooks attheir opposite ends. These hooks are adapted to engage holes or openingsin lugs 42 secured upon the receptacle and openings 48 formed in theedge of the flange 36 having connection with the packing or stuifing box32.

In Fig. 6 I have shown a modified construction of the means forconnecting or securing together the adjacent edges of the parts of whichthe body portion 1 of the receptacle and cover 8 and the collars 12 and18 are constructed. In the said modified construction the edges of thesaid parts are brought in juxtaposition with respect to each other,preferably in contact, as indicated, and are held in such position bymeans of an overlapping strip 45 which is secured to each of the saidparts by means of screws or equivalent devices 46.

My invention comprehends other improvements in details of constructionwhich will be pointed out and specifically set forth in the claims.

In the specification and claims the terms plunger and piston rod areintended to include any reciprocating member employed in mechanicalconstructions and which require lubrication.
